Chapter 2: Introduction to the 2000X aed Actuator
Glossary of Terms
Control Limits: Additional parameters that determine the end of the ultrasonic portion of the
cycle and the move to the hold state.
Converter: The device that converts electrical energy into mechanical vibrations at a high fre-
quency (an ultrasonic rate). The Converter is a central component of the welding system and is
mounted in the Actuator.
Counters: A record of the number of cycles run by category, for example, alarms, good parts,
and so on, recorded in the Controls.
Digital Filter: A smoothing technique used to provide more meaningful data.
Down Speed: The user-definable speed of descent (percentage of maximum speed) during the
down stroke of the Actuator.
Energy Mode: A mode of operation in which ultrasonics are terminated at a user-specified
energy value.
External Amplitude Control: Enables you to access real-time amplitude control directly.
External Frequency Control: Enables you to access real-time frequency control directly.
Form Feed: When using a printer with the 2000Xd Power Supply to capture weld data, you can
insert a form feed after print setup, print graph, or after reaching the number of lines per page.
Frequency: The operating frequency of the ultrasonic stack. The frequency stored is measured
at the end of the ultrasonic portion of the cycle (when ultrasonics are terminated).
Freq End: The frequency at the end of the ultrasonic portion of the welding cycle (when ultra-
sonics are terminated).
F Actual: The actual running frequency of the acoustic system.
F Memory: The frequency stored in the Power Supply memory.
Frequency Offset: An offset factor applied to the ultrasonic frequency stored in the Power Sup-
ply.
General Alarm: An alarm that occurs due to system fault and/or tripping a limit.
Ground Det. Cutoff: Ground Detect Cutoff. Immediately terminates the weld process, includ-
ing the hold step, when a ground detect has occurred.
Gnd Det. Mode: Ground Detect Mode, available in all models of 2000X power supplies. In this
mode of operation, ultrasonics are terminated after detection of a ground condition between the
horn and fixture or anvil.
Hold Force: The force on the part during the hold portion of the cycle.
Hold Time: The duration of the hold step.
Horn Down: A mode in which ultrasonics are locked out and the user can advance the Actuator
for setup and alignment.
Linear Encoder: Provides carriage (horn) distance measurement during the Actuator cycle.
Lines per Page: When using an optional Printer, the number of welds per printed page.
S-Beam Load Cell: Provides force measurement for accurate ultrasonic triggering and graphing
of force.
